Introduction to Stainless Steel

Stainless steel is a strong and durable alloy known for its excellent corrosion resistance. It is made by alloying iron with chromium, nickel, and other elements, which forms a chromium oxide layer that protects the metal. Stainless steel typically has a tensile strength ranging between 480-2,000 MPa (70-290 ksi) and a yield strength between 170-1,000 MPa (25-145 ksi), allowing it to withstand significant stress without deforming.

There are various types of stainless steel, including austenitic, martensitic, ferritic, and duplex, each offering different mechanical properties and levels of corrosion resistance. Its resilience and sleek appearance make stainless steel a popular choice for a wide range of applications, from kitchen appliances to medical equipment.

Benefits of Stainless Steel​

Our range of stainless steel includes austenitic, martensitic, ferritic, etc., that offers superior durability and corrosion resistance. The benefits of stainless steel materials include:
  • Corrosion Resistance: Long-lasting protection against rust and stains.
  • High Durability: Strong and reliable, withstands wear and tear.
  • Hygienic: Easy to clean, prevents bacterial growth.
  • Heat Resistance: Maintains strength at high temperatures.
  • Eco-friendly: Fully recyclable.
  • Aesthetic Appeal: Sleek and modern finish.

Types & Grades of Stainless Steel

Carbon steel and HSLA steel are the main types specifically classified as shipbuilding steel. Other types, like nickel steel, stainless steel, duplex stainless steel, maraging steel, weathering steel, and tool steel, are also used in shipbuilding but are not exclusively used for it.

  • Austenitic: 304, 316, 321, 347
    • Applications: Kitchenware, chemical processing, architecture.
  • Ferritic: 430, 409, 439, 444
    • Applications: Automotive exhausts, appliances, industrial equipment.
  • Martensitic: 410, 420, 440C, 431
    • Applications: Cutlery, surgical instruments, industrial blades.
  • Duplex: 2205, 2507
    • Applications: Oil and gas industry, marine environments.
  • Precipitation-Hardening: 17-4 PH, 15-5 PH
    • Applications: Aerospace, chemical, petrochemical industries.

What is stainless steel made of?

Stainless steel is made of iron, chromium (at least 10.5%), and other elements like nickel and carbon.

What is the difference between stainless steel and regular steel?

Stainless steel contains chromium, which provides corrosion resistance, while regular steel does not.

Which type of stainless steel is the best?

For most applications, austenitic stainless steel is the best due to its excellent corrosion resistance and good mechanical properties. However, the “best” depends on the specific application scenario. Other stainless steel types also have unique properties and uses.

Which grade of stainless steel is the best?

The best grade of stainless steel depends on the application, but for general use, 304 stainless steel is often considered the best due to its excellent corrosion resistance, durability, and affordability. For marine environments, 316 stainless steel is preferred due to its higher corrosion resistance.

Does stainless steel rust?

Stainless steel can rust under certain conditions, especially if the protective chromium oxide layer is damaged. However, it is much more resistant to rust compared to regular steel.
